Shared Responsibility Arising from Non-Refoulement Violations

The multiplication of actors participating in the international society and their increasing role in this context has given rise to situations, where several actors contribute to wrongful outcomes. To this general observation, non-refoulement is no exception and the contribution of several international persons in the violation of the norm is almost a daily phenomenon. Against this background, this PhD project explores the concept of shared responsibility arising from non-refoulement violations and seeks to assess the efficiency of the existing legal framework, as authoritatively codified and developed by the International Law Commission and as built on, novelly interpreted or expanded by highly qualified publicists, in addressing this complex phenomenon.
